ABSTRACT:
A low-pressure mercury-vapor discharge lamp combination for phototherapeutic treatment of infantile hyperbilirubinemia. The lamp combination includes the standard hollow elongated envelope having a coating of selected phosphors carried as a layer on the inner surface thereof. The coating of selected phosphors substantially comprises a blue-radiating alkaline-earth metal halophosphate activated with divalent europium and a second phosphor with a color output that falls within a predetermined area of an xy-C.I.E. diagram with the weight ratio of the europium-activated alkaline-earth metal halophosphate to the second phosphor being from about 90:10 to 85:15. This lamp combination substantially eliminates any tendency of the blue-radiation of the alkaline-earth metal halophosphate to produce nausea in certain attendant individuals.
